To all whom it may concern:

Be it known that I, HENRY FRANCIS Kinn,

a citizen of the United States of America, and a resident of Bronxville,in the county of Testchester and State of New York, have invented acertain new and useful Lock, of which the following is a specification,the same being a full, clear, and exact description of the invention,such as will enable those skilled in the art to which it appertains tomake and use the same.

My invention relates to appliances for securing in position doors andlike movable articles, and in particular to locks and latches adapted tobe inserted in a notch or recess in the stile of a door having a combined escutcheon and face plate.

To attain the desired end, this, my invention consists in theconstruction, arrange` ment and operation of parts herein set forth.

In order to enable the invention to be fully understood I will proceedto explain the same by reference to the drawings, illustrative of oneembodiment of the invention, which accompany and form a part of thisspecification, and in which- Figure l represents a perspective view of alock constructed according to this invention. Figs. 2 and 3 are planviews of other locks in which the invention is embodied.

Likeletters of reference indicatelike parts in all the views.

Referring particularly7 by letter to the drawings A, A1, denote mycombined escutcheon plates and face plate which rests against the sidesof a door and extends around its front edge and preferably overlaps themortise notch C, and which is preferably made of sheet metal. Thecombined escutcheon plates A and face plate A1, is of a unitaryconstruction, so far as its function in supporting within the same thelock-case D (which contains a suitable lock or latch mechanism) and inserving as a covering for the notch or recess is concerned, may beconsidered as an entirety no matter whether it is integral and is madeof a single piece of metal as shown in Fig. l, or whether it is composedof a plurality of plates rigidly f fastened together, as illustrated inFigs. 2 and 3.

B designates the knobs, and B1, the shanks i of the same whichpreferably inclose the spindle or lock-rod and ordinarily pass on saidshanks and ordinarily carried by the escutcheon plates, and rest againstthe sides of the lock-case I) which is a complete artiA cle of itselfconsisting of the body (Z and cap (Z1, and is supported within thecombined escutcheons and face plate by means of screws cl2, insertedinto the front of the lock-case through the face plate A1.

The lock-case l) is inserted into a recess, notch or mortise C formed inthe edge of the door preferably by simply sawing a piece out to thedepth of the lock, and the top and bottom edges a, al, (or as it were,flanges (l of the escutcheon plates, and extensions thereof and edges alof the face plate) being of greater dimensions or size than the openAing or recess in the door, overlap the same, and thereby entirely coveror f ame in the mortise and conceal any possible poor cutting out of thedoor, in the event of the saine being carelessly or hastily done. Thetop and bottom edges a, al, also serve to afford resistance flanges orborders or stops, in order to prevent any danger of the lock from beingpulled out of its position to any de' grec, or any lateral displacementthereof, or the bending out of shape or the `straining of any of theparts inasmuch as the said edges a, al, rest respectively against thesidesand front edge ot the door, the face plate A, also serving tosupport the lock-case.

The combined escutcheons and face plate not only forms a protection tothe wood of the door, but the said structure is very readily applied andquickly attached to the door by simply slipping the combined escutcheonsand face plate over the edge of the door and thereby inserting the lockin` the notch or recess cut out of the stile and then screwing theescutcheons to the sides of the door in the proper applied position bymeans of the screws El.

This invention is applicable to all kinds of doors to which mortise orrim locks can be attached, and is manifestly applicable to both locksand latches, or a combination of the two.

I prefer to construct the combined es cutcheons and face plate of such awidth, when formed up, as will conform to a standard thickness of adoor, and to that end the escutcheons are permanently held a certaindistance apart by the face plate, which is through the knob roses B2preferably loose fiXed in width and not laterally expansible. In caseone perpendicular edge of the door is, for any reason, in the course ofmanufacture, made uneven, in applying my combined escutcheons and faceplate, after one escutcheon is fastened to the door, the fleXible faceplate will allow the other escutcheon to be forced inwardly, ifnecessary, so as to conform to the shape or contour of the edge of thedoor without straining the parts, or bending the same out of shape. Andas the lock case is supported at one end by the face plate, and at theother by the escutcheons, when one of the lateral edges of the lock isso bent inwardly, and the adjacent escutcheon moved rearwardly, the lockspindle will be correspondingly deflected so as to lie at all timesparallel with the face plate.

In this application I claim only a combined escutcheons and lock-face ofa fixed width and madev of sheet metal, in connection with the locksupported thereby, as a combined escutcheons and expansible face plateis claimed in my co-pending application for patent 310,929.

I wish it to be understood that I do not desire to be limited to theexact details of construction shown and described, for obviousmodifications will occur to a person skilled in the art.

That I claim as my invention is- In a lock, a combined sheet metalescutcheons and face plate of a fixed width, a lock case, knob rosessupported by the escutcheons, a knob spindle passing through the lockcase, and knob shanks passing loosely through the knob roses and restingdirectly against the sides of the lock case, the whole being adapted,when assembled, to be applied to a door without dismemberment, the lockcase being adapted to be supported at one end by the face plate, and atthe other by the escutcheons, the sheet metal yieldable face plate beingadapted to hold the escutcheons a certain distance apart while beingapplied to a door, and either of the escutcheons being adapted to bemoved rearwardly relative to the other, whereby one of the edges of theface plate may be bent in wardly, and the knob spindle may becorrespondingly deflected so as to lie at all times parallel with theface plate.

In testimony of the foregoing specification I do hereby sign the same inthe city of New York, county and State of New York this second day ofApril 1906.
